Anthropology and archaeology have been augmented in recent years by nondestructive noninvasive imaging techniques. One of the coolest is backscatter muography.
Scientists used an unprecedented imaging technique called muography to
create an internal scan of the Great Pyramid of Giza. See how it
works. Muography is the process of recording the trajectories of
sub-atomic particles known as muons to form images. The process is
similar to taking an x-ray but on a much larger scale.
Muography usually takes advantage of natural muons formed in the atmosphere - so a sort of passive sensing technique. It would be possible to generate artifical muons and use them to do active sensing; this would be good for a near future fiction.
Another less edgy but also cool technique is ground penetrating radar. This is active sensing, using electromagnetic radiation to look through and into structures and the ground to determine what is under there.
Coolest of the cool: aerial lidar
What’s more, the study is yet another example of how an airborne
remote-sensing technique called light detection and ranging, or lidar,
is dramatically changing how archaeological research is done in
heavily forested regions. The technique, which uses laser pulses to
gather data on the contours of jungle- and vegetation-covered land,
has uncovered other lost ruins at the Maya city of Tikal in Guatemala
(SN: 9/27/18) and a vast network connecting ancient cities of
Southeast Asia’s Khmer Empire (SN: 6/17/16), among other finds.
I like this one best because you can look thru things to see what is underneath, then go down and walk in. That is what is going on with these Mayan ruins. People did not appreciate the extent of what that ancient civilization had built!
Your anthropologist knows where to look and what to look for. The engineer knows how to look. They are a good team.
I had a vision of the engineer whose nickname is Din. Originally it was "Odin" because he was All Seeing. People started calling him DinDin because he does not like to miss meals and it shows. Ultimately it became Din. Din is good with all of that; "It's all true."
